Dating sites for lesbians

Neurobiologist Robert Sapolsky constructed a reproductive spectrum with opposite poles being tournament species, in which males compete fiercely for reproductive privileges with females, and pair bond arrangements, in which a male and female will bond for life.These species-particular behavior patterns provide a context for aspects of human reproduction, including dating.

Dating is a stage of romantic relationships in humans whereby two people meet socially with the aim of each assessing the other's suitability as a prospective partner in an intimate relationship or marriage.

It is a form of courtship, consisting of social activities done by the couple, either alone or with others.

Thus, the concept of marriage is changing widely in many countries.

Historically, marriages in most societies were arranged by parents and older relatives with the goal not being love but legacy and "economic stability and political alliances", according to anthropologists.

As humans societies have evolved from hunter-gatherers into civilized societies, there have been substantial changes in relations between men and women, with perhaps one of a few remaining biological constants being that both adult women and men must have sexual intercourse for human procreation to happen.

Humans have been compared to other species in terms of sexual behavior.
